Description

Technical Field

[0001] The present invention relates to the technical field of flange installation, and specifically provides an auxiliary installation device and method for offshore wind power flanges. Background Technique

[0002] A flange, also known as a flange convex disc or a flange, is a part used for connecting shafts to each other and is used for connecting pipe ends. When connecting two pipes using flanges, in order to ensure the accuracy of the butt joint between the flanges, it is necessary to ensure the concentricity of the two flanges to prevent deviation of the two pipes after butt joint.

[0003] However, when installing flanges by butt joint, most of the existing methods are to set a device similar to a crane on the hull, set a fixing mechanism on the flange, and then move the flange through the lifting ropes set on the fixing mechanism.

[0014] An auxiliary installation device for an offshore wind power flange. The usage steps of the auxiliary installation device for the offshore wind power flange are as follows: Step 1: First, weld the first body and the wind power pipe on the base. Then, move the device to a suitable position. Then, erect the second body. At this time, start the two second cylinders. The two fixed blocks move closer to fix the outer wall of the lower wind power pipe. Step 2: Pass the lower end of the support member through the lower end of the first body placed on the two protrusions. Then, start the first motor in the forward direction. The first motor drives the second gear to rotate. Then, through the second rack, the two pressing plates are moved out of the second sleeve to fix the top of the upper wind power pipe. As the first motor starts, the first cylinder starts to rotate. Then, through the first connecting frame, the driving ring is driven to rotate. At this time, the first gear rotates, driving the first rotating shaft to rotate, and the plurality of support plates are rotated out to support and fix the lower end of the first body. Step 3: After the wind power pipe on the first body is fixed, move it above the second body, and move the first body towards the welded second body until the first body moves into the detection range of the vision detector. Then the vision detector starts to detect. When the holes of the first body and the second body are aligned, the vision detector detects the image on the detection board. Use a welding machine to perform on-site welding at the connection between the upper end of the second body and the upper end of the wind power pipe. After welding is completed, implement Step 4. When the vision detector does not detect the image on the detection board, the controller controls the cylinder three to clamp the second body through the clamping plate, and then the motor two starts to rotate the second body until the holes of the first body and the second body are aligned. After alignment, use a welding machine to perform on-site welding at the connection between the upper end of the second body and the upper end of the wind power pipe. After welding is completed, implement the following Step 4; Step 4: Reverse the motor one, and multiple support plates and the abutting plate all move back to their original positions and no longer fix the first body. At this time, the first body slides down along the two limit frames two under the limiting action of the two limit frames two until the lower end surface of the first body fits with the upper end surface of the second body, completing the fixed installation of the two first bodies and the second body.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: The stable structure composed of the support members, reinforcement members, linkage members, etc. of the device of the present invention can effectively resist the interference of external factors such as sea breeze and sea waves during the installation process. Even in a harsh marine environment, it can ensure the smooth progress of the flange installation process, reducing the probability of installation accidents caused by external environmental factors. For example, a stable support structure can prevent the device from tipping or displacing under the action of wind and waves, thus avoiding a series of safety accidents caused thereby, providing a safer and more reliable working environment for the offshore wind power flange installation operation. Compared with the traditional flange hoisting method, since the lifting rope is easily affected by the sea breeze and sways, the operator faces greater safety risks when docking the flange. The device of the present invention greatly reduces the exposure time and operation frequency of personnel in dangerous areas through an automated installation process. The operator only needs to start the device at a relatively safe position and monitor the installation process, effectively reducing the risk of casualties caused by accidents such as the swaying of the lifting rope and the slipping of the flange, and ensuring the life safety of the construction personnel.

[0016] The design of the entire device of the present invention is highly automated, and the various components work together through a precise linkage mechanism. For example, during the installation process, it is only necessary to start motor one and cylinder two to automatically complete a series of operations such as fixing the main body one and the wind power pipe inside it, unfolding the support parts, and positioning the reinforcement parts, without the need for a large amount of manual intervention and complex manual adjustment. The cooperation between the visual detection mechanism and the controller realizes real-time monitoring and automatic error correction of the installation process, greatly shortening the adjustment time during the installation process. Compared with the traditional lifting method, the present device significantly improves the installation speed of the offshore wind power flange, and can complete more installation tasks in a shorter time, effectively shortening the construction period of the offshore wind power project and improving the overall economic benefits of the project. The support parts and reinforcement parts in the installation assembly cooperate with each other to provide extremely stable support and fixing conditions for the flange installation. A plurality of equidistantly distributed support plates can accurately unfold and support the lower end of the main body one under the action of the linkage parts. At the same time, the abutment plate of the reinforcement part can firmly abut the top of the wind power pipe. This all-round stability The support structure effectively prevents the flange from being displaced or shaken due to external force during the installation process, further ensures the accuracy of flange installation, makes the pipeline connection more stable and reliable, and improves the operating stability of the entire offshore wind power system. In addition, the offshore wind power flange auxiliary installation device of the present invention is equipped with a visual detection mechanism. Through the accurate recognition of the detection plate image by the visual detector, the relative position of the main body one and the main body two can be monitored in real time. Once a deviation is found between the hole positions of the main body one and the main body two, the controller can quickly control the motor two and the cylinder three to work, and use the clamping plate to accurately adjust the main body two to ensure that the concentricity of the two flanges is within a very small error range. This automated detection and adjustment mechanism greatly improves the accuracy of flange docking, effectively avoids errors that may be caused by manual measurement and adjustment, thereby further increasing the safety of operators during operation, thereby ensuring the quality of offshore wind power pipeline connections, reducing pipeline leakage, stress concentration and other problems caused by insufficient installation accuracy, extending the service life of offshore wind power facilities, and reducing later maintenance costs.

[0017] The design of the mobile assembly of the present invention makes it extremely convenient to move and position the device on the offshore platform. The multiple mobile wheels at the lower end of the base are driven by the coordinated drive of motor three and motor four to achieve precise steering and position adjustment. When switching between different wind power pipeline installation positions, the device can be quickly and accurately moved into place, reducing time waste during equipment transfer. At the same time, the adjustment mechanism can flexibly adjust the height and angle of the installation assembly, so that it can quickly adapt to different installation scenarios and operating requirements, further improving the efficiency of the installation operation and avoiding installation delays due to insufficient equipment adaptability.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-7 , the present invention provides a technical solution: an auxiliary installation device for an offshore wind power flange, including a first body 1 and a second body 2, and further including, An installation component, including a support member 3 provided at the lower end of the first body 1, a reinforcement member 4 provided at the upper end of the first body 1, a linkage member 5 provided inside the first body 1, and an auxiliary installation member 6 provided at the second body 2. The support member 3 drives the reinforcement member 4 to work synchronously through the linkage member 5 to form a linkage; The support member 3 includes a plurality of support plates 30 distributed at equal intervals. One end of each of the plurality of support plates 30 is fixedly connected to a first rotating shaft 31, a first gear 32 fixedly provided on the outer wall of the first rotating shaft 31, a first rack 33 meshed with the first gear 32, and a driving ring 34 fixedly connected to the first rack 33. By rotating the driving ring 34, the first rack 33 can be driven to move, thereby rotating the first rotating shaft 31, and then rotating the support plates 30 to the lower end of the first body 1 to realize the support function for the first body 1; The reinforcement member 4 includes a second gear 40, two symmetrically distributed second racks 41 meshed with the second gear 40, and a pressing plate 42 fixedly connected to one end of the second racks 41. One end of the two second racks 41 close to the pressing plate 42 is L-shaped. A second rotating shaft 43 is fixedly connected to the inner wall of the second gear 40, and one end of the second rotating shaft 43 is fixedly connected to the output shaft of a first motor 44. When the first motor 44 is started, the second gear 40 can be driven to rotate, so that the second racks 41 drive the pressing plate 42 to move out of the second sleeve 51 to reinforce the top of the wind power pipe in the first body 1; And a moving component 7, the moving component 7 is used to move the installation component, and the moving component 7 is provided at one end of the first body 1 and the second body 2.

[0021] The linkage member 5 includes a first sleeve 50 fixedly installed at the upper end of the driving ring 34, a second sleeve 51 movably connected to the upper end of the first sleeve 50, a first cylinder 52 fixedly installed at the lower end of the second rotating shaft 43, a first connecting frame 53 fixedly connected to the lower end of the first cylinder 52, and a reinforcing frame 54. The lower end of the first connecting frame 53 is fixedly connected to the upper end of the driving ring 34 to drive the driving ring 34 to rotate. A reinforcing frame 54 is slidably connected to the inner wall of the second sleeve 51. A connecting column is fixedly connected to the lower end of the reinforcing frame 54, and a second connecting frame 55 is fixedly connected to the lower end of the connecting column. The side wall of the second connecting frame 55 is slidably connected to the inner wall of the driving ring 34. A reinforcing plate 56 is fixedly connected to the lower end of the second connecting frame 55. A plurality of the support plates 30 are movably arranged on the upper end of the reinforcing plate 56. The linkage member 5 can enable the support member 3 and the reinforcing member 4 to form a linkage working mechanism. During use, when it is necessary to fix the top of the wind power pipe, the first motor 44 is started. The output shaft of the first motor 44 drives the second rotating shaft 43 to rotate. Since the second gear 40 is fixedly connected to the second rotating shaft 43, the second gear 40 rotates synchronously. The rotating second gear 40 interacts with two symmetrically distributed and meshing second racks 41, causing the two second racks 41 to move relative to or away from each other along the radial direction of the second gear 40 depending on the rotation direction of the first motor 44. Because one end of the second rack 41 is fixedly connected to a pressing plate 42, the pressing plate 42 moves out of the second sleeve 51 as the second rack 41 moves, gradually approaching the top of the wind power pipe until the pressing plate 42 closely fits against the top of the wind power pipe, completing the fixing operation of the top of the wind power pipe. With the start of the first motor 44, since the lower end of the first cylinder 52 is fixedly connected to the upper end of the driving ring 34 through the first connecting frame 53 and the first cylinder 52 is fixedly installed at the lower end of the second rotating shaft 43, when the first motor 44 drives the second rotating shaft 43 to rotate, the first cylinder 52 also rotates synchronously around the axis of the second rotating shaft 43. The rotation of the first cylinder 52 drives the first connecting frame 53 to rotate, and the first connecting frame 53 further drives the driving ring 34 to rotate. The rotation of the driving ring 34 causes the first rack 33 fixedly connected to it to move. The movement of the first rack 33 drives the first gear 32 meshing with it to rotate. Since the first gear 32 is fixed on the outer wall of the first rotating shaft 31, the first rotating shaft 31 also rotates accordingly. The rotating first rotating shaft 31 causes the connected support plate 30 to rotate around the axis of the first rotating shaft 31, gradually rotating out from the initial retracted position to support and fix the lower end of the first body 1. When the flange installation is completed, it is necessary to perform a reset operation on the device for the next use or to move the device. At this time, the first motor 44 is started in the reverse direction. The first motor 44 drives the second rotating shaft 43 to rotate in the reverse direction, and the second gear 40 also rotates in the reverse direction, causing the second rack 41 to drive the pressing plate 42 to move into the second sleeve 51, returning to the initial position. At the same time, the first cylinder 52 rotates in the reverse direction, driving the first connecting frame 53 to rotate in the reverse direction, and the driving ring 34 also rotates in the reverse direction. Through the transmission of the first gear 32 and the first rack 33, the first rotating shaft 31 rotates in the reverse direction, and the support plate 30 retracts to the initial retracted state.With the arrangement of the first sleeve 50, the second sleeve 51 movably connected to the upper end of the first sleeve 50, the first cylinder 52 fixedly installed at the lower end of the second rotating shaft 43, the first connecting frame 53 fixedly connected to the lower end of the first cylinder 52, and the reinforcing frame 54, the distance between the support plate 30 and the abutting plate 42 can be adjusted by the telescopic movement of the first cylinder 52, so as to fix and move the first body 1 and the wind power pipe of different heights, reducing the limitation of the device in use.

During the installation process, the second cylinder 60 can control the movement of the fixed block 61 to achieve the preliminary fixation of the lower wind power pipe, thus facilitating the fixation work of the wind power pipe and the support work of placing the second body 2 on the lower wind power pipe. Thus, the visual detection mechanism 67 can accurately detect the relative position of the flange.

One end of the second limiting frame 73 close to the first body 1 is an arc surface and matches the shape of the first body 1. The first limiting frame 72 and the second limiting frame 73 play a role in limiting and guiding during the installation of the device, ensuring that the first body 1 can move vertically towards the second body 2, so that the first body 1 and the second body 2 can be accurately docked.

[0029] An offshore wind power flange auxiliary installation device. The usage steps of the offshore wind power flange auxiliary installation device are as follows: Step 1: First, weld the first body 1 and the wind power pipe on the base 70. Then, move the device to a suitable position. Next, erect the second body 2. At this time, start the two second cylinders 60, and the two fixing blocks 61 move closer to fix the outer wall of the lower wind power pipe. Step 2: Pass the lower end of the support member 3 through the lower end of the first body 1 placed on the two protrusions 712. Then, start the first motor 44 in the forward direction. The first motor 44 drives the second gear 40 to rotate, and then drives the two pressing plates 42 to move out of the second sleeve 51 through the second rack 41 to fix the top of the upper wind power pipe. With the start of the first motor 44, the first cylinder 52 starts to rotate, and then drives the driving ring 34 to rotate through the first connecting frame 53. At this time, the first gear 32 rotates, driving the first rotating shaft 31 to rotate, and turning out multiple support plates 30 to support and fix the lower end of the first body 1. Step 3: After the fixation of the first body 1 and the wind power pipe on the first body 1 is completed, move them above the second body 2. Move the first body 1 towards the welded second body 2 until the first body 1 moves to a suitable position, that is, until the first body 1 moves into the detection range of the vision detector 670. Then, the vision detector 670 starts to detect. When the hole positions of the first body 1 and the second body 2 are aligned, the vision detector 670 can detect the image on the detection plate 671. Use a welding machine to perform on-site welding at the connection between the upper end of the second body 2 and the upper end of the wind power pipe. After the welding is completed, step 4 can be implemented. When the vision detector 670 does not detect the image on the detection plate 671, the controller controls the third cylinder 69 to clamp the second body 2 through the clamping plate 66. Then, start the second motor 63 to rotate the second body 2 until the hole positions of the first body 1 and the second body 2 are aligned.
